Yes, until/unless the child is adopted.
No they are not.
Signing rights away will not stop any child support from being taken from the father. If the child is the fathers then he is financially responsible for the child weather he has rights or not.
Parents are financially responsible for their children until they reach the age of 18. After their children are adults it is up to them to take care of themselves, although many parents may still help.
Children had no 'rights'. The parents had complete control over their families.
No, they have no control over a 21 year old son and are not responsible.
You have full and primary rights to your children. Grandparents do not have custody rights to children over parents.
I'm not a lawyer or anything near it, but to the best of my knowledge the parent who is retaining their rights can request that the parent relinquishing theirs still be held financially obligated. I've also heard that in the case that the request is not made, the parent relinquishing their rights is still responsible for any arrears owed.
When someone marries, he is legally bound to one spouse and is not supposed to marry another without divorce. Financially, they are supposed to support each other and a spouse gets some rights over the marital property.
Why should adult children have any rights to the personal gains of a parent, unless they worked to add to them?
Even if you've given up parental rights, you'll still have to pay child support if it's been determined that you are the biological father. Child support is not payment to see the child. It's designed to help the primary custodial parent support the child in a single parent household.
I'm not sure what you mean by this since children don't have any rights over their parents, remarried or not. If he is ill and need guardianship you can apply for that in court but if he is a normal healthy adult you have no rights at all just like he has no rights over you once you became adults.
Yes, when you marry him. No, he doesnt get custody over you and your son just because he is 19. If your married to him you and the boy are dependents, meaning he is financially responsible. Just being boyfriend and girlfriend has no legal boundaries. He doesnt just get the baby either. The mother usually has the inherent rights over baby unless father takes her to court to fight for custody.
